Claims.

This invention relates to improvements in car-end platform buffingmechanism for railway cars.

One object of the invention is to provide a bufling mechanism includingthe usual end platform, buffer face plate, and spring resisted sidestems for supporting the face plate from the platform, wherein thebuffer side stems are made readily removable without disturbing theother parts of the mechanism by providing the bulfer face plate with anopening through which the side stem may be bodily withdrawn, andproviding detachable means for anchoring the buffer stem to the faceplate which normally obstructs the opening through which the stem isremovable.

Other objects of the invention Will more clearly appear from thedescription and claims hereinafter following. 7

In the drawing forming a part of this specification, Figure 1 is afragmentary top plan view of a buffing device for railway cars embodyingmy invention, certain parts being broken away to show one of the bufferstems in plan. Figure 2 is a longitudinal vertical sectional view,corresponding substantially to the line 2--2 of Figure 1. Figure 3 is adisassembled view of the separated parts at the front end of themechanism, showing the retainer pin in side elevation, the face plate invertical section, supporting bracket in side elevation, and the frontend portion of the buffer side stem in side elevation. Figure 4 is afront elevational view of a portion of the buffer face plate. Figure 5is a detailed,

perspective view of the supporting bracket for the buffer side stem.

Referring to the drawing, my improvement is shown in connection with awell-known type of bufiing mechanism including the'usual end platformll] of a passenger car, having a central pocket II in which the frictionshock absorber l2 of the buffing mechanism is accommodated, and acentral bufi'er stem l3 engaging the friction shock absorber. The endplatform is provided with the usual opening l4 through which the centralbuffer stem extends and in which it is guided. At opposite sides of thecentral bulTer stem, the platform It] is provided with the usuallengthwise extending openings I 5-45 through which the buffer side stemsextend and rear supporting members or brackets Iii-l6 also provided withguide openings for guiding the buffer side stems.

In carrying out my invention, I provide broadly a buffed face plate Asupported by a pair stems 3-3; and a pair C-C seated over the B-B, thebulfer face of spring opposed side of supporting brackets front ends ofthe stems plate being provided with openings D-D therethrough, throughwhich the buffer side stems maybe passed, and which openings are blockedby the brackets 0-0 to preclude removal of the side stems.

The buffer face plate A, which is supported forwardly of the platform IDby the side stems BB, comprises a vertical front Wall l1, and top andbottom, rearwardly projecting, horizontal flanges l8 and I 9. Atopposite sides, I provide the face plate A with the openings D-D, whichare of square outline and extend through the wall I1 and arerespectively in alignment with the two buffer side stems. The openings DD are of such a size as to permit the buffer stems to pass freelytherethrough in lengthwise direction. As seen in Figure 2, each openingD has the top and bottom sides thereof spaced appreciably from theflanges l8 and IQ of the face plate A, thus providing abutment faceportions 20-40 above and below the opening.

The buffer side stems B-B, which are disposed at opposite sides of theplatform ID, are of like design. Each stem comprises a cylindrical,rod-like rear end section or shank 2| and an enlarged front end section22 of square cross section. A shoulder 23 is thus provided between thefront end section 22 and the shank section 2|. At the extreme front endthereof, the section 22 has a vertical pin receiving opening 26extending therethrough. Each buffer side stem B is provided with theusual spring 25 which surrounds the stem and bears at its front and rearends respectively on a. collar 26 on the section 2| ofvthe stem,abutting the shoulder 23, and a collar 21 on the rear end of the sectionabutting the bracket l6 of the platform It). Each stem also has theusual retaining nut. 28 at the rear end thereof which abuts the rearside of the bracket l6 and limits forward movement of the stem B and theattached buffer face plate A.

The supporting bracket 0-0 are of like design, each bracket being in theform af a U- shapedmember having a vertically extending transverse frontwall 29 and rearwardly projecting, top and bottom, vertically spacedflanges 30 and 3| extending from the wall 29. The bracket C is of such avertical height that it practically fills the opening between the topand bottom flanges I8 and I9 of the face plate A and is provided with aforwardly projecting central lug 32, on the wall 29, which is of squarecross to connect the side stem to the bracket and-to.

the face plate, the'latter being provided with aligned openings 35-35 inthe flanges I8 and 19 thereof to accommodate the pin.

In the assembled condition of the-parts of the buffer mechanism, asshown in Figures 1 and 2,

the forward ends of the buffer sidestems- -B-B- 5 are secured to theface plate A'by the pins 34-35 which extend through the openings 35-35of the face plate, the openings 33-33 of the supporting brackets C-C andthe openings 2 4-2 2 of the side stems B-B, thereby 0-0 in place andmounting the face plate for holding the brackets pivotalmovement'with'respect to each side stem. To removeeither buffer sidestem B, the-pin 34' 1 disengaged from the' stem and-bracket C; and

the stop nut 28 removed from the rear end of the stem. The supportingbracket'C' andthe buffer stem are then pushed inwardly as a: unitto-such an extent that sufficient clearance is rearwardly of the buffertachment of the bracket 0 from the stemv 'After the bracket C has beendetached, the bufferstem is withdrawn, through the opening D of thebuffer face plate A bypassing the stem lengthwise through said openingin forward direction.
